Brock Palen and Jeff Squyres speak with Matt Knepley and Jed Brown about the PETSc (http://www.mcs.anl.gov/petsc/petsc-as/) scientific toolkit. Jed Brown is a PhD student at ETH Zürich, working on solvers for ice sheet dynamics. His research interests are in scalable solvers for unstructured high-order discretizations of indefinite and multirate problems. He has been using PETSc since 2004 and contributing regularly for the past year. Matthew G. Knepley received his B.S. in Physics from Case Western Reserve University in 1994, an M.S. in Computer Science from the University of Minnesota in 1996, and a Ph.D. in Computer Science from Purdue University in 2000. He was a Research Scientist at Akamai Technologies in 2000 and 2001. Afterwards, he joined the Mathematics and Computer Science department at Argonne National Laboratory (ANL), where he was an Assistant Computational Mathematician, and a Fellow in the Computation Institute at University of Chicago. In 2009, he joined the Computation Institute as a Senior Research Associate. His research focuses on scientific computation, including fast methods, parallel computing, software development, numerical analysis, and multicore architectures. He is an author of the widely used PETSc library for scientific computing from ANL, and is a principal designer of the PetFMM and PetRBF libraries, for the parallel fast multipole method and parallel radial basis function interpolation. He was a J.~T. Oden Faculty Research Fellow at the Insitute for Computation Engineering and Sciences, UT Austin, in 2008, and won the R&D 100 Award in 2009 as part of the PETSc team. RCE 23: Gromacs

Brock Palen and Jeff Squyres speak with Dr. David van der Spoel about Gromacs a free MD package. David van der Spoel is a professor in Computational Molecular Biophysics at the university of Uppsala, Sweden. He received his Ph.D. in 1996 from the university of Groningen in the Netherlands, under the supervision of Prof. Herman Berendsen. Since 1997 he is associated with Uppsala University. He is one of the lead developers of the GROMACS molecular simulation software and has been involved in software development for high-performance computing for more than two decades. His research interests are in automated development of models for molecular simulations, and studies of proteins under non-physiological conditions, most notably in the gas-phase. He is also involved in development of web-services for molecular modeling. RCE 21: SC09 Supercomputing 09

Brock Palen and Jeff Squyres speak with Dr. Bill Gropp of University of Illinois Urbana-Champaign William Gropp is the Paul and Cynthia Saylor Professor in the Department of Computer Science and Deputy Directory for Research for the Institute of Advanced Computing Applications and Technologies at the University of Illinois in Urbana-Champaign. He received his Ph.D. in Computer Science from Stanford University in 1982 and worked at Yale University and Argonne National Laboratory. His research interests are in parallel computing, software for scientific computing, and numerical methods for partial differential equations, and he is well known for the MPICH2 and PETSc libraries. Richard Graham has been at ONRL since Jan, 2007 and is the Group Leader for the Application Performance Tools group in the Computer Science and Mathematics division at ONRL, and is a Distinguished member of the Research Staff. Prior to joining ORNL he spent eight years at ORNL serving in a range of technical and managerial roles, leaving as the acting group leader for the Advanced Computing Laboratory. He is currently chairman of the MPI Forum, and is leading the MPI-3 effort. He led the LA-MPI development effort, and is one of three founders of the Open MPI project. Dr. Graham received his PhD in Theoretical Chemistry from Texas A&M University in 1990, and a BS in Chemistry from Seattle Pacific University in 1983. RCE 20: Silo

Brock Palen and Jeff Squyres speak with Mark Miller on the Silo (wci.llnl.gov/codes/silo) storage format. Mark also works on the Visit (wci.llnl.gov/codes/visit) project which were our guests on RCE 6. Be sure to catch Jeff and Brock at SC09 this year in Portland! Mark received his Ph.D. from U.C. Davis in EE with emphasis on compression of very large datasets for real-time signal processing. I started at LLNL in May of 1995 working on I/O analysis of Silo. From there, I became involved in the ASCI Data Models and Formats effort leading the development of the Sets and Fields (SAF, pronounced 'safe') data modeling system where I also became involved in scalable, parallel I/O. Then, I moved to VisIt, adding scalable rendering as my first major enhancement. Since then, I have been working about 50-75% time on VisIt, 25% time on Silo and, more recently, on ITAPS SciDAC project. More Articles... |
